for example if someone ask you to go camping fuck off would mean, no i won't be joining you, i thank you so much for the invitation but i check my agenda and unfortunately im unavailable, you know fuck off!

When a guy is repeatedly turned down by a girl- whether it be turned down for hand holding, making out or banging- and continues to try to get it in. Listen dude- ITS NOT GONNA HAPPEN. Face it, you messed up big time and because of that she's just not that into you...at all. So get it together, stop crying at bars annnnd don't show up on her doorstep weeping about what a pathetic little bitch you are. You fucked up and now you are being instructed to fuck off.
